What the kids did is wrong. However, The reason it is *so* wrong, is the hysteria surrounding sexual offenses.
Accusing anyone of this offense may have dire consequences even though no charges are pressed. We are so far past reasonableness when it comes to accusations of pedophilia that I had a moment of hesitation when I googled pedophilia for spelling.
When a person can be required to register as a sexual offender for "peeing in the bushes", (yes, I'm exaggerating), none of us are safe. A witch-hunt mentality seems to have taken over.
On one hand, The kids did a horrible thing, even worse than posting a sign in your front yard that so and so is a pedophile. On the other hand, it's horribleness is a direct consequence of the witch-hunt mentality. I'm so confused.
